ABSTRACT 
In the sphere of construction contracts where the two 
parties Client and Contractor are involved it is 
characteristic to anticipate the susceptibility of the 
construction projects to many variation claims which 
generally cover a vast scope. These claims include 
Increase of Cost and/or Time Extensions. 
This research which has been limited to the subject of 
Time Extension Claims has been done with the objective of 
enlightening the NWS&DB Engineers with the problems 
associated in Time Extension Claims. 
In order to achieve this target a familiarization was 
found necessary of the Conditions of Contract (ICTAD 
1989),, Government Financial Regulations (Ministry of 
Finance 1992) and delegation of Financial Authority 
(NWS&DB 1991), which have been studied in relevance. . 
It was found practically helpful and interesting to 
analyse a number of case studies from various construction 
contracts that were relevant to Time Extension Issues in 
order to give better expression to the subject under 
scrutiny, thus enabling achievements of the required 
objectives.
